Seriously...

Can a robot host a radio show? Georgia Lewis-Anderson is a conversation designer for voice technology, writing answers to the more human questions that people ask voice assistants like 'what's your favourite food', 'will you marry me' or 'what's the meaning of life'. As voice assistants become better and better talkers, Georgia is doing an experiment to test whether she can push their chit chat to the limit by making a LoveBot driven by AI that can host a relationship advice radio phone-in. Building the bot, she unravels how our conversations with computers work, explores ethical concerns, and shines a light on the ways more and more of us are looking to machines to help with our emotions.

The comedian Russell Kane traces his success back to the day his Dad bought his council house in Enfield in the 80s. Now, in 2019, he wrestles with the impact of the Thatcher policy which allowed that to happen – Right to Buy. Russell’s family lived in an end of terrace, which meant a bigger garden, and the potential for an extension. His Dad built pillars onto the entrance of the house and, in his most audacious of moves, hand-dug a 21-foot swimming pool. The house became known as “The Castle” to their disgruntled neighbours, and Russell started to feel different. He felt he could strive for more and he thinks it was the trigger for the events which led him to university, and beyond. In all the debate about housing and the Right to Buy policy, Russell thinks that the social impact on families like his has been forgotten. But he also feels like the drawbridge was pulled up behind him – as if his family’s luck was potentially to the detriment of others. The social housing in Enfield was depleted, and his co

The Corrections re-visits four news stories which left the public with an incomplete picture of what really happened. In August 2017, The Times published a piece with the headline ‘Christian child forced into Muslim foster care’. The story was front-page news the next day as well - and the next – but was it right?

Shappi Khorsandi’s life is disorganised. A single mother of two and a stand-up comedian and writer, Shappi is busy. She doesn’t know what money is coming into or out of her account, her love of charity shopping is getting out of control, her prized family photographs are shoved in a box in the back of the wardrobe and the clutter is overwhelming. She's tried the famous Marie Kondo method of tidying up, but it hasn't helped a bit. She hates being disorganised. She wants to do something about it! Should Shappi just learn to embrace the chaos? Or can professional help put her life in order? Produced by Amy Wheel for BBC Cymru Wales

Generation Z is self-taught. No-one any older really gets that. The children born around the turn of the millennium came into a digital world and had to find out for themselves how to navigate it. Sure, we all live it now - but we weren't formed by it. We came to digital from the safety of adulthood. In this programme, six wise school-leavers take us on their digital journey in their home town of Huddersfield. Simone has lived there her whole life and is about to leave for university. But before she goes, she's joined by a group of her friends who take us around Huddersfield and back through their digital adolescence. They tell us their stories of self-education, from friendship to flirting, memes to messaging, and talk about the lessons that they had to learn. Presenter: Simone Dawes Producer: Camellia Sinclair

The story of Scotland's deadly drug crisis narrated by the voice of the narcotic itself. Scotland has the highest rate of reported drug deaths in the European Union. There has been a rapid rise of cheap, imported synthetic drugs - especially Etizolam, an illegal tablet similar to Valium but with an unpredictable potency often many times higher. But why do so many people, especially young men, feel drawn towards this dangerous self-medication? Scottish poet Niall Campbell explores the lives and deaths of a small number of drug users and of their families in Dundee. Using original music by Jon Nicholls and found sound, Niall’s poem weaves through first-hand accounts of the addictive process to create an elegy to the lost and those they leave behind. The Ballad of the Fix is a companion piece to The Ballad of the Blade (2018) in which Momtaza Mehri listened to the voices of young people involved in knife crime. Producers: Monica Whitlock and Liza Greig If you’ve been affected by addiction, help and support is av

Gemma Cairney brings together artists from two different countries to combine their talents to make a new piece of music. In this episode Gemma invites 24-year-old London rapper Loyle Carner to Guyana, South America to join flautist and composer Keith Waithe, a leading figurehead and champion of Guyanese culture. Loyle aka Benjamin Coyle-Larner was raised in Croydon South London by his Scottish mother and stepfather. His biological father is of Guyanese descent, but he has never visited the country. Loyle earned a Mercury Prize nomination for his debut album Yesterday’s Gone in 2017. His second album Not Waving, But Drowning was released earlier this year exploring everything from his ADHD and the pains of moving away from home, to his mixed race heritage. His other passion is food and he launched the Chilli Con Carner cookery school for kids growing up, as he had, with ADHD. Loyle will be immersed in the culture, food and music of Georgetown, working with Keith and other traditional Guyanese musicians to

LGBTQ+ venues are closing across the UK. Research from the UCL Urban Laboratory indicates that, since 2006, the number of venues in London has fallen from 125 to 53 - with some still at risk of closure. Conversely, there's been a 144% increase in hate crimes against LGBTQ+ people, with one in five experiencing a hate crime this year. Performance artist and writer Travis Alabanza asks if the venues have served the purpose they were originally built for or if now, more than ever, LGBTQ+ people need these spaces. Speaking to Professor Ben Campkin from UCL, Travis finds out why individual venues are closing and the impact of their loss. Travis hears personal accounts of how these venues shapes individuals, and visits one of London’s oldest LGBTQ+ venues, The Black Cap, which closed in 2015. Campaigners have since held weekly vigils there, but developers want to turn the upper part into luxury apartments and say a new pub will have an "LGBT flavour". Travis also visits a venue being threatened with closure, The

We hear from one of the world’s last remaining globemakers and reflect on the globe’s cultural and symbolic currency. While Google Earth may give us intricate detail of every inch of land, there’s nothing like clutching a globe to properly comprehend our place in the world. We’ve been fascinated by replicating our planet since ancient times; an art and science that’s developed as our understanding has evolved. In this programme, we step into the studio of Bellerby & Co Globemakers, one of the few companies remaining that are making globes by hand today. From their Stoke Newington warehouse, we follow the journey of a globe from design to dispatch. We hear about the challenges they face daily, from retraining their hands to querying geopolitical protocol, and the customers who’ve commissioned their unique bespoke worlds. Alongside this creative process, we visit installation artist Luke Jerram, who is touring his replica earth artwork, Gaia. We also hear from writer and cartography enthusiast Simon Garfield

Why do you keep going back to the fridge after dinner? Fruit and vegetables, a balanced diet, low salt, low sugar and moderate exercise seem to be the silver bullets loaded into a revolver that has only ever fired blanks at the problem of Britain’s obesity crisis. More than ten years ago, the celebrity chef Jamie Oliver came to Rotherham in an effort to help combat obesity, by providing information on how to cook healthy foods. A decade on Rotherham still has a high proportion of people that are overweight or obese. In What’s Eating Rotherham, local resident Joanne Keeling, who is 28 stone and trying to lose weight, looks at the emotional side of overeating and examines the effect Jamie Oliver - and the spotlight he brought to Rotherham - can have on a town at the centre of media attention. With the help of Producer Jay Unger, Joanne soon discovers an uncomfortable truth about why some people emotionally eat. As well as questioning whether or not traditional methods of treating obesity, like prescribed exerc

In an age of certainty, of assertions without facts, and sometimes assertions with facts, Mark O’Connell makes the case for a different virtue – ambivalence. Six years on from his thought-provoking, witty and charming Four Thought, he returns to make the case for ambivalence. In those six years almost every trend in public life has been away from ambivalence rather than towards it. Populist movements from the left and the right are about certainty, and even the idea of balance often ends up sharing single, entrenched views, just neatly arrayed on either side. Yet in real life few decisions are truly clear-cut, there is often a case on both sides, and a reasonable person could easily reach a different conclusion with the same evidence. Most of us, much of the time, have complex and mutually contradictory views on issues small and large. And that's also true in public life: the arts and business, politics and the military are all properly in the realm of ambivalence, with complicated, messy and marginal decis

David Baker, contributing editor of Wired, explores the challenges Facebook must meet and overcome in order to survive after a disastrous period which has seen the reputation and the business model of the social media giant questioned like never before. Producer: Jonathan Brunert

Lucy Cooke sets out to discover why honesty is almost certainly not the best policy, be you chicken, chimp or human being. It turns out that underhand behaviour is rife throughout the animal kingdom, and can be a winning evolutionary strategy. From sneaky squid, to cheating cuckoos, some species will resort to truly incredible levels of deception and deviousness to win that mate, or get more food. And when it comes to social animals like we humans, it turns out that lying, or at least those little white lies, may be the social glue that binds us all together. Lucy heads to the RSPB cliffs at Bempton, with Professor Tim Birkhead to discover why so many bird species appear to be such proficient deceivers, as well as visiting the very crafty ravens at The Tower of London. She speaks to psychologist Richard Wiseman about how to spot when someone is lying, and finds out whether she is any good at it. In fact, can we trust any of what she says in this documentary at all?

Hannah Jane Walker argues that sensitivity is overlooked, dismissed and under-utilised, and argues that our society would be much better off if we embraced it instead. Two years ago, Hannah gave a Four Thought talk about sensitivity, and received hundreds of emails from strangers, reaching out to tell her the same things: that sensitivity in our society isn’t considered useful, and that, well, ‘that’s just the system that we live in, isn’t it?’ Since then, Hannah has felt slightly ashamed at having started such a powerful conversation without offering a solution. And so in this programme she sets out to do just that. She’ll be talking to several of her correspondents, as well as a psychologist, a neuroscientist, an economist and even a newly-minted activist for the highly sensitive. The programme focuses on highly sensitive people, but sensitivity is a spectrum and as Hannah hears more about it, she also finds out more about the benefits all of us can take from being in closer touch with our sensitive sides

Anxiety has become one of the defining characteristics of our modern age, with millions of us suffering from its various damaging effects. It comes in many shapes and sizes - status anxiety, social anxiety, and more recently Brexit and Eco-anxiety. Figures indicate a big rise in its prevalence, particularly among young people and members of minority groups. In this editon of 'Archive on Four' Professor Andrew Hussey how this new age of anxiety has come about, how it compares with previous moments of national stress, and also why he believes it to be a peculiarly modern phenomenon. Hussey makes the case that while pathological forms of anxiety can be crippling, anxiety can also bring with it positive benefits - and rather than attempt to destroy it we should attempt to make it a useful ally.

What happens when top graduates work behind bars as prison officers? Lucy Ash meets young people who have forsaken lucrative careers in the City or elsewhere, for what many see as one of the world’s worst jobs. They’re part of Graduates Unlocked, a scheme which, which is trying to replicate in the prison service the success of Teach First, the programme that sends high-flyers into inner-city schools. The aim is to raise the status and reputation of prison officers, to boost recruitment and cut reoffending. It is hoped that youthful enthusiasm plus resilience and empathy could bring a much needed revolution to the criminal justice system. But faced with acute understaffing and assaults on prison officers at record levels, how much of a difference can the graduates make? Lucy meets a group of young men and women who are are sent to HMP Aylesbury, which holds the longest-sentenced young adult males in the English prison system. The youth offender institution in Buckinghamshire is "in a perpetual state of crisi

A tense debate is taking place in states across America. At what age should someone be allowed to marry? Currently in 48 out of 50 states a child can marry, usually with parental consent or a judge's discretion. In 17 states there's no minimum age meaning in theory a two year old could marry. But there's a campaign to change the law and raise the minimum age of marriage to 18 without exceptions across all American states. But changing the laws state by state is not as easy as one may think. There's resistance and raising the minimum age to 18 has often been blocked by legislators. Jane O'Brien speaks to child brides, the campaigners pushing to make it illegal and the people who say that the laws don't need to change. Producer: Rajeev Gupta Editor: Amanda Hancox

Hate seems to be everywhere - whether it’s white supremacists marching on the streets of America, jihadists slaughtering Christians in Sri Lanka or the massacre of Muslims in New Zealand. In this five part series, BBC journalist Allan Little unpicks the mechanics of hatred and reveals how this dangerous emotion has been whipped up and disseminated throughout history. Allan Little begins with the hatred he witnessed on the killing fields of the Bosnian War, deconstructing how Serbian leaders like Slobodan Milosevic and Radovan Karadzic manipulated and weaponised history to inculcate a violent loathing that would lead to the massacre of thousands of Bosnian Muslims at Srebrenica. It's a hatred and an ideology that continues to inspire today's extreme far-right. Presenter: Allan Little Producer: Xavier Zapata Editor: Helen Grady

While the video games industry is big business, it's also breaking new ground in the arts. We're at a cultural tipping point for the industry. For the past decade the process of producing and distributing games has become easier so there's now a wider array of games than ever before. And games, which are the meeting point for so many art forms, are now at the forefront of creativity, pushing boundaries and making players think differently. In this programme, Alex Humphreys speaks to leading video games designers, composers and writers from around the world about their craft, and discovers the ongoing battle to have video games recognised on a par with other creative mediums.

Radio 1 Breakfast Show host Greg James digs into the BBC's archives, taking some of the week's news stories as a starting point for a trip into the past. Greg, who describes himself as a "proud radio nerd", is let loose in the vast BBC vaults, home to a treasure trove of radio and television programmes as well as some revealing documents. He says "As someone who spends too much time searching for oddities online, the opportunity to gain access to one of the greatest media resources on the planet was too good to miss." This audio journey uncovers some surprising moments. As the UK prepares for the state visit of President Trump, Greg discovers some of his first encounters with British broadcasters - and also finds that searching for 'trump' in the archives delivers an unexpected series from the early 1980s. The Elton John biopic Rocketman arrives in our cinemas this week and the BBC archives reveal that Elton's journey to global success had a very bumpy start. And following the announcement that Yorkshire-b
